In my experience with the Campine. I have noticed that the females seem to moss out easily. Guessing by the color that is expressed on the pullets I would say that she is pure Brakel, but due to poor selection has lost the ability to keep the barring as crips in her older years. I notice your male seems to have a yellow tent as well this could explain some of the loss of barring as well. As a breeder that has delt with similar breeder birds, I recommend hatching a lot of birds and cull based on color. You should see improvement. I started with goldens that had silver blood in them and after close selection I have eliminated a great deal of the mossiness out of my line.
